Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques01:30

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

52
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

259
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

778
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Oxygen Delivering System III: Tracheostomy and T-piece

2.0K
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Suctioning the Oropharyngeal Airway

331
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Cardiopulmonary Resuscitation II: ACLS Airway Management

71
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Area of Science:

  • Pulmonology
  • Infectious Disease Control
  • Medical Device Engineering

Background:

  • The COVID-19 pandemic highlighted the need for enhanced safety during aerosol-generating procedures like bronchoscopy.
  • Precise knowledge regarding SARS-CoV-2 transmission risk during bronchoscopy was lacking.
  • The Ankara University Bronchoscopy Cabinet (Aubrocab®) was developed as a protective barrier device for healthcare professionals.

Purpose of the Study:

  • To evaluate the effectiveness of the Aubrocab® in preventing aerosol spreading during bronchoscopy.
  • To quantify the reduction in airborne particles within the bronchoscopy suite using the Aubrocab®.

Main Methods:

  • A comparative study design was employed, categorizing patients into two groups: those undergoing bronchoscopy with and without the Aubrocab®.
  • Particulate Matter (PM) 0.5 levels were measured in the bronchoscopy suite before and after the procedures in both groups.
  • Statistical analysis was performed to compare particle levels and changes between the two groups.

Main Results:

  • A total of 82 patients were included, with 62 utilizing the Aubrocab®.
  • Pre-procedure PM 0.5 levels were comparable between groups.
  • Post-procedure PM 0.5 levels were significantly lower in the Aubrocab® group (42,603 ± 8,632 vs. 50,377 ± 10,487, p = 0.001).
  • The percentage change in particles and the absolute difference in particle numbers pre- and post-procedure were also significantly lower with Aubrocab® use (p < 0.003).

Conclusions:

  • The Aubrocab®, a novel barrier device, effectively prevents excessive aerosol release during bronchoscopy.
  • The device serves as an additional safety measure beyond routine precautions.
  • Implementation of Aubrocab® can enhance protection for healthcare workers during aerosol-generating procedures.
